SAMUEL HIOKOK, OF BUFFALO, NEW YORK.

CAR-COUPLING TOOL.

SPECIFICATION forming part of Letters Patent No. 236,156, dated January4, 1881.

Application filed June28, 1880. (No model.) i

To all whom tt may concern Be it known that I, SAMUEL HIoKoK, ofBuffalo, in the county of Erie and State of New York, have inventedcertain new and useful Improvements in Gar-Oouplin g Tools; and I dohereby declare the following to be afull, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

My invention relates to a device for handling car-coupling links in theact of coupling cars together without the operator standing between thecars; and the novelty consists in the construction and adaptation of theimplement for that purpose, as'will be more fully hereinafter set forth,and specifically pointed out in the claims.

For the successful manipulation of the link in coupling cars together,so as to have the link enter the jaw of the draw-head, not only must thelink be lifted or depressed, but in many cases it must be pulled orpushed forcibly to or from the operator, or, in other words, must beforced transversely. In order to do this efficiently the implement mustbe capable of seizing the link between devices that will lock it ineither direction and allow both vertical and transverse motions. Toaccomplish this end various devices have been producedsuch, forinstance, as spring-jaws, which, while they may allow a slightmanipulation of the link, can only lift the link by the main force ofthe operator, and are not adapted to pull the link forcibly toward theoperator, for the reason that the spring-jaws would open and release thesame. Rigid jaws have also been used; but these have been only efficientwith a twisting o'r rotary motion of the implement in either direction,and possibly. to push away from the operator; but to forcibly andquickly pull the link toward the operator they were not reliable, as theamount of friction necessary to hold the link against a smoothjaw couldnot always be determined, and wear by such friction made it still moreunreliable. To

avoid these difficulties, and to provide a perfect and reliable lock'tothe implement upon the link, this invention is designed.

In carrying out my invention I employ a shank-of sufficient length,having upon one end a transverse handle to give great rotary power tothe device, and upon the other end curved transverse arms, which, at aproper distance from the plane of the shank, assume a form parallel tosaid plane. One of these jaws is made longer than the other, enablingthe operator to press the upper or inner side of this long jaw againstthe. upper or under surface of the link, and then, by pushing theimplement and rotating it slightly, insures a proper and certain hold. Ialso provide the inner surface of the jaws, upon each side, with abevel,which, acting upon a similar bevel upon the locking arms or lugs, servesas a steady bearing for the link, and assists materially in theefficient operation of the implement.
